PACEMAKER(8) System Administration Utilities PACEMAKER(8) NAME Pacemaker - Part of the Pacemaker cluster resource manager SYNOPSIS crm_mon [options] DESCRIPTION Provides a summary of cluster's current state. Outputs varying levels of detail in a number of different formats. OPTIONS Help Options: -?, --help Show help options --help-all Show all help options --help-output Show output help --help-display Show display options --help-additional Show additional options --help-deprecated Show deprecated options Output Options: --output-as=FORMAT Specify output format as one of: console (default), html, text, xml, none --output-to=DEST Specify file name for output (or "-" for stdout) --html-cgi Add CGI headers (requires --output-as=html) --html-stylesheet=URI Link to an external stylesheet (requires --output-as=html) --html-title=TITLE Specify a page title (requires --output-as=html) --text-fancy Use more highly formatted output (requires --output-as=text) Display Options: -I, --include=SECTION(s) A list of sections to include in the output. See `Output Con- trol` help for more information. -U, --exclude=SECTION(s) A list of sections to exclude from the output. See `Output Con- trol` help for more information. --node=NODE When displaying information about nodes, show only what's re- lated to the given node, or to all nodes tagged with the given tag --resource=RSC When displaying information about resources, show only what's related to the given resource, or to all resources tagged with the given tag -n, --group-by-node Group resources by node -r, --inactive Display inactive resources -f, --failcounts Display resource fail counts -o, --operations Display resource operation history -t, --timing-details Display resource operation history with timing details -c, --tickets Display cluster tickets -m, --fence-history=LEVEL Show fence history: 0=off, 1=failures and pending (default with- out option), 2=add successes (default without value for option), 3=show full history without reduction to most recent of each flavor -L, --neg-locations Display negative location constraints [optionally filtered by id prefix] -A, --show-node-attributes Display node attributes -D, --hide-headers Hide all headers -R, --show-detail Show more details (node IDs, individual clone instances) --show-description Show resource descriptions -b, --brief Brief output Additional Options: -i, --interval=TIMESPEC Update frequency (default is 5 seconds) -1, --one-shot Display the cluster status once and exit -d, --daemonize Run in the background as a daemon. Requires at least one of --output-to and --external-agent. -p, --pid-file=FILE (Advanced) Daemon pid file location -E, --external-agent=FILE A program to run when resource operations take place -e, --external-recipient=RCPT A recipient for your program (assuming you want the program to send something to someone). -W, --watch-fencing Listen for fencing events. For use with --external-agent. Deprecated Options: -h, --as-html=FILE Write cluster status to the named HTML file. Use --out- put-as=html --output-to=FILE instead. -X, --as-xml Write cluster status as XML to stdout. This will enable one-shot mode. Use --output-as=xml instead. -s, --simple-status Display the cluster status once as a simple one line output (suitable for nagios) -N, --disable-ncurses Disable the use of ncurses. Use --output-as=text instead. -w, --web-cgi Web mode with output suitable for CGI (preselected when run as *.cgi). Use --output-as=html --html-cgi instead. Application Options: -$, --version Display software version and exit -V, --verbose Increase debug output (may be specified multiple times) -Q, --quiet Be less descriptive in output. NOTES Notes: If this program is called as crm_mon.cgi, --output-as=html and --html-cgi are automatically added to the command line arguments. Time Specification: The TIMESPEC in any command line option can be specified in many dif- ferent formats. It can be an integer number of seconds, a number plus units (us/usec/ms/msec/s/sec/m/min/h/hr), or an ISO 8601 period speci- fication. OUTPUT CONTROL Output Control: By default, a particular set of sections are written to the output des- tination. The default varies based on the output format: XML includes all sections by default, while other output formats include less. This set can be modified with the --include and --exclude command line op- tions. Each option may be passed multiple times, and each can specify a comma-separated list of sections. The options are applied to the de- fault set, in order from left to right as they are passed on the com- mand line. For a list of valid sections, pass --include=list or --ex- clude=list. INTERACTIVE USE Interactive Use: When run interactively, crm_mon can be told to hide and show various sections of output. To see a help screen explaining the options, press '?'. Any key stroke aside from those listed will cause the screen to refresh. EXAMPLES Display the cluster status on the console with updates as they occur: crm_mon Display the cluster status once and exit: crm_mon -1 Display the cluster status, group resources by node, and include inac- tive resources in the list: crm_mon --group-by-node --inactive Start crm_mon as a background daemon and have it write the cluster sta- tus to an HTML file: crm_mon --daemonize --output-as html --output-to /path/to/doc- root/filename.html Display the cluster status as XML: crm_mon --output-as xml AUTHOR Written by Andrew Beekhof and the Pacemaker project contributors Pacemaker 2.1.7 May 2025 PACEMAKER(8)
